Made from 100% Polyester, this Decepticon over-the-shoulder book bag doubles as a backpack!  One could say it "Transforms," from one to the other.  HAH!  The front flap closes with a clip and features a giant Decepticon Symbol in devious white, blue and purple!  This bag defaults to messenger bag form with an adjustable strap. But turn it around, unzip the top zipper and you'll discover 2 adjustable straps.  Congratulations, you just entered...Backpack Mode!  This Transformers bag also features multiple pockets for multiple...things!  As a member of the human race who has sided with the Decepticon faction of Transformers, prepare to be.......punched in the neck!
